Arlington, Texas ? Juan Gonzalez was placed on the 15-day disabled list Wednesday because of a strained right calf, a move that could hamper attempts by Texas to trade the two-time AL MVP before next week’s deadline.

The move is retroactive to Sunday, a day after Gonzalez left the Rangers’ game at Tampa Bay after getting hurt while running the bases. He won’t be eligible for activation until Aug. 4.

Gonzalez was at the ballpark, but wasn’t in the clubhouse before the Rangers’ game against Anaheim and didn’t participate in batting practice.

Texas purchased the contract of first baseman Jason Jones from Triple-A Oklahoma. He was in the starting lineup as the designated hitter for his major league debut.

Manager Buck Showalter said Gonzalez wouldn’t be ready to play again for at least a week. But Showalter doesn’t believe that will make it impossible to trade the slugger who is hitting .294 with 24 homers and 70 RBIs in 82 games.
